Cook using good sieve (7)
I believe the answer is:
griddle
'cook' is the definition.
(to cook with a griddle)
'good sieve' is the wordplay.
'good' becomes 'g' (abbreviation).
'sieve' becomes 'riddle' (riddling is a kind of sieving).
'g'+'riddle'='GRIDDLE'
'using' acts as a link.
(Other definitions for griddle that I've seen before include "Is it a hot surface" , "Flat heated surface used for cooking" , "Iron plate for cooking on" , "Circular iron plate used for baking" , "cooking accessory" .)
